Specification of Letters Patent.

Application flied June 16, 191;. Serial No. 773,971.

'To all whom it may concern:

Be it known that 1, WILLIAM A. JEx, a citizen of the United States, residing at No. 88 Adams street, in the city-of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

My invention relates to improvements in a rotary valve for internal combustion engines, especially in the means for mounting same and in the provision for the intake of the fuel, and for the exhaust of the burned gases through stationary water cooled diag-' onal passageways inside the rotary valve and it has for its'primary object to provide an improved valve, in which the moving parts for controlling the fluid contents of the explosion space shall be positively acting, perfectly cooled and gas tight, and further to provide a very desirable opening, such as a quick opening, a long dwell and a'quick closing of large ports.

According to the present invention I provide a cylinder having a closed and an open end with the ports for induction and exhaust and a reciprocating piston operating therein. Mounted on the closed end of the a cylinder I provide a valve chamber, containing a stationary passageway cylinder, telescoped by a cylindrical rotating valve which may be in the form-of a single rotating cylinder or in the form of an inner and outer cylinder respectively adapted to rotate in opposite directions.

With these ends in view, the invention consists in certain features of novelty in the construction, combination and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being had to the accompanying drawings, forming a part of this specification, wherein:

Figure 1 represents a longitudinal section through the head of one unit of an internal combustion engine fitted with a rotary valve constructed and arranged according to this invention. Fig. 2 represents a longitudinal section at right angles to Fig. 1 through thehead of a two cylinder internal combustion engine built up from units such as are shown in Fig. -1 showing the arrangement of the intake and exhaust passageways through the stationary valve cylinder in the rotary valve. Fig. 3 shows in longitudinal section a modified construction of an internal combustion engine with a valve formed of inner and outer cylinders adapted to rotate in opposite directions, showing the exhaust valve open. Fig. 4 is a similar section show- 1ng the position of the inlet ports when the valve is in the position shown in Fig. 3. Fig. 5 represents another modification from that shown in Figs. 3 and 4 showing the arrangement of an inner and outer valve cylinder.

Throughout the drawings like parts are designated by similar reference characters.

Referring to the drawings 2 represents the rotary valve 3 the valve chamber extension and 4 the fixed or stationary "alve cylinder. The said extension 3 is preferably cast integral with the working cylinder 1 and its.

hollow interior forms the. valve chamber.

The inlet and exhaust ports 5, 6 respectively are formed in the cylinder head and the inlet and exhaust ports 5", 6 respectively are formed in the extension 3 said ports being arranged diagonally opposite each other and in different planes as shown in Fig. 2. The inlet and exhaust passageways 7,. 8 respectively in the stationary valve element 4 are formed to register with the ports 5*, 6 in the cylinder head and 5 6" in the extension aforesaid, between which the ported rotary valve 2 is adapted to be rotated so as to cut off and establish communication at the proper times between the said ports in the cylinder head and the ports in the extension through the passages 7 and 8. The rotary valve is provided with two inlet ports diagonally opposite and two exhaust ports diagonally opposite each other and in dif-' convenient .intermediate transmission gear. In either of the two arrangements of valves shown the valve would require to be rotated at half speed of the crankshaft, for an engine working'on a four stroke cycle.

Both the stationary valve element 51 and the extension 3 are provided with water jackets 9, 10 respectively as shown, and in the former case said jacket 9 communicates with the ordinary cylinder jacket by the passages 11 and 12.

faces. To prevent the escape of the gas longitudinally of the surface of the valve 1' provide the packing rings 13, inserted between the valve ports substantially "as shown inFig.2.

In Figs. 3, 4 and 5 I show a modified construction of the rotary valve of my invention. the drawings, is here' formed of an inner and outer cylinder 1% and 15 respectively adapted to be rotated in opposite directions by means of suitable transmission gearing. The said cylinders 14 and 15 are extended as shown and are provided with toothed sprocket wheels 16 and 17 at their extremities which are rotated from the crankshaft at the proper speed through any convenient j The said intermediate transmission gear. cylinders 14 and 15 are provided withtwo inlet ports diagonally opposite and two exhaust ports diagonally'opposite each other in 'diii'erent'plan'es to correspond with the 7 ports in the cylinder head and extension.

it will be obvious that as the cylindersli and 15 are rotated in opposite directions they will cut oii and establish communication at the proper times between the ports in the cylinder head and in the extension through the passages 7 and 8. By the arrangement of the said pair of valve cylinders rotating in oppositedirections obtain an enlargement of the ports and effect a more rapid opening and closing of said a p01 ts.

The-operation: At the moment when the ports in the valve are registering with the inlet ports of the cylinder the piston is descending and creating a suction, the'oharge is then compressed by the next stroke of the piston: and ignited at the next stroke. At the moment ofignition the engine shaft has accomplished one complete revolution, while both :ports-in the cylinder have been closed during the compression and ignition. On the continued rotation of the shaft the exhaust port is opened and the gases escape on the next stroke ofthe piston, thus com pleting a cycle of four strokes of the piston for every revolution of the valve. I do not wish to be understood as limiting myself to the exact details of oon'struction shown and described, as they may' be The valve is thus sur-" rounded on all sides by water cooled sur-H The rotating valve, as shown in.

variously modified within the spirit and intended scope of my invention. For instance two separate valve chambers and valves may be employed one for inductionan'd one for exhaust without afi'ectin the principle of the valve mechanism. uitably arranged ball bearings may be employed between the valve end .and the cylinder extension if found necessary.

As shownin Figs. 2 and 5 the exhaust ports may be united and lead to one conduit, while the induction ports may be similarly united by adding more units.

Having" nowparticularly described and ascertained the nature of my said invention and in what manner the sameis-to be performed, I declare that What l claim is:
